I may upgrade my camera to a d80 which has commander mode. Am I correct in my thinking that I'd be better off selling my sb-800 and adding a bit of money to get two sb-600's? Obviously, if I stick with my D60 it won't matter because I won't be able to do off camera flash with either choice. Is the extra bit of power worth keeping the sb-800? What about high speed sync, the sb-600 doesn't do that does it? I honestly am not sure if I'm going to do more indoor or outdoor photography, so I'm not sure if indoor lighting would outweigh outdoor high speed sync or not. What are your thoughts?
